Conical Twin Screw Extrusion Machine Configuration

  • force feeder
  • soft plasticization screw and barrel
  • high precision gearbox
  • exhaust system

Conical Twin Screw Extrusion Machine Plastic Extrusion Process

  • plastic materials are gravity fed from a hopper into a jacketed screw.
  • As the screw turns about its axis, it transports, melts, and pressurizes the plastic.
  • From the metering section, the plastic enters the front flange of the die, which is bolted onto the end of the extruder barrel.
  • It flows around the mandrel, suspended in the center of the channel.
  • At the rear of the mandrel, a pin and a land size the product.
  • When the product leaves the die, it enters a vacuum chamber where it is pulled through sizing rings. The combination of vacuum pulling and air pressure forces the plastic to conform to the shape of the rings. The vacuum chamber is water-filled, which cools the plastic into a hard solid.
  • The cooled product is then pulled by haul-off unit and is cut to length or coiled up.

Conical Twin Screw Extrusion Machine Main Features:
1. Model SJZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound.

With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.

2. The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.

3. The conical twin screw extruder system has applied special computer control. According to customers’ requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.

4. The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.

5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.

6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.
